    # File lib/packetfu/protos/ipv6/header.rb, line 14
    def initialize(args={})
            super(
                    Int32.new(args[:a1]),

### Public Instance Methods

read(str) click to toggle source

Reads in a string and casts it as an IPv6 address

    # File lib/packetfu/protos/ipv6/header.rb, line 38
    def read(str)
            force_binary(str)
            return self if str.nil?
            self[:a1].read str[0,4]
            self[:a2].read str[4,4]
            self[:a3].read str[8,4]
            self[:a4].read str[12,4]
            self
    end

read_x(str) click to toggle source

Reads in a colon-delimited hex string and casts it as an IPv6 address.

    # File lib/packetfu/protos/ipv6/header.rb, line 49
    def read_x(str)
            addr = IPAddr.new(str).to_i
            self[:a1]=Int32.new(addr >> 96)
            self[:a2]=Int32.new((addr & 0x00000000ffffffff0000000000000000) >> 64)
            self[:a3]=Int32.new((addr & 0x0000000000000000ffffffff00000000) >> 32)
            self[:a4]=Int32.new(addr & 0x000000000000000000000000ffffffff)
            self
    end

to_i() click to toggle source

Returns the address as a fairly ginormous integer.

    # File lib/packetfu/protos/ipv6/header.rb, line 28
    def to_i
            (a1.to_i << 96) + (a2.to_i << 64) + (a3.to_i << 32) + a4.to_i
    end

to_s() click to toggle source

Returns the address in string format.

    # File lib/packetfu/protos/ipv6/header.rb, line 23
    def to_s
            self.to_a.map {|x| x.to_s}.join
    end

to_x() click to toggle source

Returns the address as a colon-delimited hex string.

    # File lib/packetfu/protos/ipv6/header.rb, line 33
    def to_x
            IPAddr.new(self.to_i, Socket::AF_INET6).to_s
    end
